A further object of the invention is to provide an improved ratchet orscrew operated well cylinder valve puller which will be secured-upon theupper end of a, well casing and attached to the plunger or sucker rodwhereby the samemay be pulled from the casing upon the operation of thesaid ratchet or screw jack} r I Another object of the invention is toprovide an improved well cylinder valve puller which. will be highlyefiicient in operation and relatively, in-

expensive to manufacture and produce.

Another object of the inventionis to provide a portable well cylindervalve puller comprising a tubular body adapted to be seated upon theupper end of a well casing or pipe and to support a screw member whichwill be secured to the plunger or sucker rod of the pump, together withinterconnected gearing which will be either operated as a screw jack ora ratchet jack for lifting the plunger or sucker rod with the valve froma well casing.

Other objects will appear as the description proceeds. r

Like characters of reference are used throughout the followingspecification and the accompanying drawings to designate correspondingparts.

In carrying out the invention, there isprovided a hexagonal tubular bodyI formed with a, centrally disposed bore 2, and an interiorly formedannular seat {adjacent its lower end, which will l or twelve ermine thnP --$I Q:-Of th exi rwrir ie ed nu hisiibnu inteer Bi! a outtheou e sure -o i 1, JTM h mi e 3 i x integrallywith the upper end of the tubularbody I and is adapted to loosely support the bevel gear i0 upon it whichis not only provided with the bevel gear teeth I I, but also with theperipheral gear teeth l2.

The bell crank operating lever or handle i3 is also loosely mounted uponthe laterally extending rod or stud 9 to the outsideof said bevel gearl0, and is held thereon by means of the cotter pin M which extendsthrough an aperture l5 formed transversely through the outer end of saidrod or stud. The short arm of the bell crank operating lever or handleis designated by the refer-' enoe numeral 16 and supports the stop shaftll, which in turnsupports the pivoted ratchet tooth or dog l8, whichwhen turned to one side will 39 cause the rotation of the gear wheel inone direction, and when the dog is turned to the opposite side the gearwheel will be operated in a reverse direction;

The elongated jack screw l9 extends loosely through the nut I and isthreaded through the bevel gear 20 extending across the upper end orsurface of the said nut I, and is intermeshed with the bevel gear I0,whereby rotation of the bevel gear ID will rotate the bevel gear 20,which 9 in turn will cause the elongated jack screw to be either raisedor lowered, depending upon the direction of rotation of said bevel gear20'. The lower end of the jack screw i9 is reduced and is externallythreaded as at 2|, and is adapted to id be threaded into the internallythreaded socket in the upper end of the plunger or sucker rod 22 uponwhich the valve packing 23 is supported. A guide washer 24 is placedabout the lower end or thejack screw I9 to serve in forming a bearing asthe plunger or sucker rod is withdrawn or replaced. Heretofore, it hasbeen necessary to install a complicated mechanism including a block andfall and a derrick whereby the sucker rod or plunger may be pulled froma well casing or pipe, but with the improved apparatus hereinbeioredescribed and illustrated in the accompanying drawings. it will be seenthat the matter of pullinga well cylinder valve will only be a matter ofminutes at the most.

As before mentioned, the pivoted dog will be turned to one side foroperating the jack screw in one direction to pull the plunger or suckerrod from the well casing, and the. dog or ratchet will be turned to theotherlside and op'erated-f tofscrew the jack screw in the oppositedirection'foireplacing the plunger or sucker rod.

cient form of well cylinder valve puller, which will, be relativelyinexpensive to produce.

manufacture and 1 While the preferred embodiment ef theinstant inventionhas been illustrated and describedyit'- will be understood that'it isnot intended to limit the scope of the invention thereto, as many minorchanges in detail of construction maybe resorted to without departurefrom the spirlt'o'f the invention.

Having thus described my invention,--*what" I claim as new and desire tosecure by Letters Patent of the United States is? A well cylinder valvepuller including. a tube detachably seated on a well casing, said tubehaving a depending retainin collar'adapted to eng5 -931,'551"- gagearound the upper end of the casing and an upwardly facing annularshoulder adjacent the upper end thereof, a supporting blockhaving a 4central bore received in the upper end of the tube and seated on saidshoulder and having a lateral flange on the upper end thereof receivedon the upperend of th e tube,,a jack screw reciprocably g mountedins'aidhore and extending'finto the well casing; a" coaxially reducedthreaded inner end on said screw for positioning in a sucker rod in Fromthe foregoing description, it will be parent that there has been deviseda highly eflie 1;.

the well casing, a bevel gear rotatably supported ;-.'onisaid'supporting block and having a center threaded bore for operativelyreceiving the jack screwy-stud extending laterally from the upper ,endof the tube,- a bevel ear complementary to the bevel gear on the blockrotatably received on'said stud and ratchet means for rotating saidgears to actuate said jack screw.
